The prices do not look correct. I believe the Royal Oak chrono RG is closer to $ 70K on bracelet and on strap it is around $ 45K. I believe the VC prices are much more reasonable on strap and bracelet. the Breguet is in the lower 30s, maybe at most being $35K for strap and I think your price around $55K is correct.

The modern Breguet Marine chrono uses a Breguet 583 which is based on the lemania 1350. I do not believe they sold this to any other company. It is derived from a lemania 1340 used in the omega moon watch with major updates. It is a very robust, bidiectional, fly back chrono movement with nice finishing and a well finished rotor. Among collectors it is not the same quality of a fp 1185, not half price in retail value. In my opinion it is only slightly less in terms of quality of design, however finishing today is top notch and made completely by Breguet.

this is a very hard comparison between AP, Breguet and VC. While Breguet and VC have limited lines in the Marine and Overseas collection, AP has so many options. The AP Royal oak that has a f piguet 1185 retails around $65k USD but you are comparing a 41mm gold watch to a 44mm gold watch in the Breguet. Glenn comparison in price was against a ROO which is close to being correct price wise.

In terms of value, Breguet remains the best in terms of bang for the buck, positioning of the brands can be a different discussion, however I believe they are all on par in terms of history, product and brand perception today.

The main difference in the pricing that you see is the pricing strategy of the brands. AP and VC have seen huge price increases both before the 2008 bust and also in the last 3 year up to 3 times in a year. To my knowledge, breguet has only taken 2 or 3 total in 5 years.

I the end of the day it all depends on demand that dictate price. for AP the RO is the centerstone of the brand and commands the highest price. For Breguet, i think the sales are very evenly distributed across all product lines which may explain them keeping the prices low across the board.
